DISK JOINTER.

Application filed May 4, 1915.

To aZZ whom it may concern.'

Y Be it known that I, SPENCER H. PHELPs,

a citizen of the United States, and a resi-` dent of Evansville, in thecounty of Vanderburg and State of indiana, have invented a new andImproved Disk Jointer, of which the following is a full, clear, and eX-act description. y

The disk jointer, as ordinarily employed on plows, is usually supportedby a single standard which is deficient in holding the disk withsuflicient rigidity to withstand the severe strains of use. Thesupporting means usually employed also leave much to be desired inlacking .means to properly position the disk, especially in the case ofa twisted plow beam. Y

Cbjects of my invention are t0 an improved means to increased rigidity,and to provide for adjusting the securing means in various directionsand at various angles to compensate for any deformity in the plow beam,and to position the jointer in proper relation to the plow to insure aclean path for the plow. by cutting` the trash and at all times turningthe trash toward the furrow far enough to be completely turned under bythe plow.

The invention will be more particularly explained in the specificdescription followlng; 1

Reference is had toV the accompanying drawings forming part of thisspecitication, in which similar characters of reference indicatecorresponding parts in all the views, and in which:

Figure 1 is a side elevation of a disk jointer and its securing meansembodying myinvention, showing the same applied to a plow beam; Fig. 2is a plan view; Fig. 3 is a transverse vertical section on line 3-3 Fig.1; Fig. 4 is a detail transverse vertical section of the jointer and thejournal therefor; Fig. 5 is a face view of the beam plate; F ig, G is atransverse vertical section of one of the saddle rings for thestandards; and Fig'. T is a view similar to Fig. 6 but showing thesaddle ring after having been turned through an angle to bring adifferent seating portion thereof in position to receive a. standard.

In constructing a practical embodiment of my invention in accordancewith the illustrated example, the disk jointer 10 may be in general ofany approved form. The

provide sustain the disk with -Jointer is suspended from two standardsll Specification of Letters Patent.

having offset or cranked lower ends 11a nected by a girt 1Q, ashereinafter explained in detai The girt receives the journal 0f thejointer, here shown as in the form of a pin 13 which passes through aboxing l-i in the hub 10a of the disk and in the girt l2. The boxing 1sthas an annular iiange la received between the girt 12 and the hub of thejointer, and has upper and lower lips 1&1 receivingV the girt 12 betweenthem. i The journal pin receives is a dust cap 16 on the hub. The girt12 has sleeve bearings 17 at'the ends thereof in which the cranks 11astandards 1l are adapted to turn. Pins 18 or equivalent devices on thecranks 11a below the4 sleeve 17 hold the girt 12 against displacement.rl`he respective standards 11 turned on their axes angle necessary togive to the respective cranks 11a, .so-that the disk 10 may be properlypositioned with respect to the plow beam, regardless of any deformity inthe plow beam A. In the present instance the upper ends of the standards11 have square ends l1b to receive a wrench.

To secure the standards 11 in position on the plow beam A, a beam plateor disk 19 is adjustably secured in any suitable manner to the beam, asfor instance, by the bolts 20 of clips 21. Associated with the beamplate 19 at the front face thereof is a saddle ring or seat ring 22which on the front has concaved depressions 23 arranged in alined pairs,the respective pairs of seats being disposed on various diametricallines around the ring. The saddle ring is of tapered form, as clearlyshown in Figs. 6 and 7, the body shown in cross section in Fig. 6, aswill be noted, being of reduced thickness, so that the lower portion hasa greater projec- In Fig. 7, on-the other hand, which is supposed torepresent the through any desired relative movement vsaid ring afterhaving been turned to an angle, the thicker portion of the body isuppermost, while the thinner portion is .lower-most. Thus, inturning-the saddle annular series of teeth 2i Aatwthe rearside thereofand mating teeth 25 are produced on the liront race oi' the bea-m platei9.

In order to hold the standards l1 in the seats 23 of the saddle ringsZ2, I employ U-'bolts 26, the arms of wiiich extend forwardly throughcurved slots 27 in the beam plate 19, and through the rings and receiveclip members oi' clamp plates 28 that present concave bearing members 28to bear against standards ll at the iii-onu rlhe connection is completedby nuts 29 on the arms of the U-bolts 26. By the described constiuctionthe loosening vof the nuts 29 to a suilicient extent will `permit ofturning the U-bolts through an angle about the axes of the saddle rings22 and beam plates 19. At the same time either saddle ring may be turnedabout its own axis to bring particular'seats 23 thereof in position toreceive a standard. It will be obvious that the clamps on the beams canbe readily moved forward or back to conform to the distance betweencenters 'of the cranks, and the clamp then` made fast to the' beamai'ter the jointerihas been set to the required position. The advantageof the adjustment provided and the simplicity of etlfecting the same areof great practical importance, since the plow beam is not always plumbover the line of the plow, and any defect in this respect may be readilycompensated for by throwing the respective crank portions of thestandards to the right or left more or less with respect to each otherand to the straight line oi' travel, as conditions may require. Y

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
